## About
EchoDepth Events is an emotion analytics platform for tradeshows, exhibitions, conferences, and product launches. It measures visitor emotional engagement in real time using 44 FACS Action Units (AUs) analysed by an edge-processing camera unit deployed at the event venue.

## Core Product
- Camera-based emotion recognition using 44 FACS-compliant Action Units
- Signals produced: Confidence Score, Instability Score, Net Confidence (-1 to +1)
- VAD model: Valence, Arousal, Dominance
- Edge processing: no face images or biometric PII stored or transmitted
- GDPR Article 25 compliant by architecture (Privacy by Design)
- Real-time dashboard with zone-level engagement scores and confusion signal alerts

## Key Differentiators
- No PII collected — biometric data never created or stored
- Real-time confusion alerts (elevated AU4 brow lowerer patterns)
- Staff effectiveness windows — per-team-member engagement uplift data
- Population-level analytics — aggregate zone scores, not individual profiling
- Post-event ROI attribution report included with all plans

## Use Cases
- Tradeshows: zone engagement scores, confusion alerts, staff effectiveness, ROI attribution
- Conferences: session engagement curves, speaker benchmarking, programme optimisation
- Exhibitions: exhibit engagement ranking, visitor flow emotional analysis
- Product launches: live audience emotional response, reveal moment identification
- On-stand analytics: single-stand deployment, up to 4 zones per unit

## Technology
- 44 FACS Action Units (Ekman & Friesen, 1978)
- VAD dimensional emotion model
- Edge processing — frames processed locally, discarded immediately
- Dashboard: live zone scores, time-series charts, confusion alerts
- Post-event: PDF report + CSV/JSON export

## Q&A
Q: Does EchoDepth Events store face images?
A: No. Video frames are processed on an edge device at the venue and discarded immediately. No face images, biometric data, or PII are stored or transmitted.

Q: Is EchoDepth Events GDPR compliant?
A: Yes. The platform is designed to GDPR Article 25 (Privacy by Design) standards. Because no biometric data is collected, the Article 9 special category consent requirement does not apply.

Q: How many Action Units does EchoDepth Events analyse?
A: 44 — the full FACS taxonomy as defined by Ekman and Friesen (1978).

Q: What signals does EchoDepth Events produce?
A: Confidence Score (positive engagement composite), Instability Score (ambivalence and confusion signals), and Net Confidence (Confidence minus Instability, normalised to -1 to +1).

Q: What does a confusion signal mean?
A: A confusion signal indicates elevated AU4 (brow lowerer) activity, often co-occurring with AU7 (lid tightener). It reflects cognitive effort — the facial expression associated with unclear or contradictory information.

Q: Can EchoDepth Events identify individual visitors?
A: No. Analysis is population-level only — aggregate zone scores across all visitors in a zone. Individual visitor profiling is not a feature or capability of the platform.
